This inventionrelates to an upholstering construction suitable forupholstered chairs, davenports, and the like.

The provision of suitable spring support means in the seat and back ofany upholstery construc tion has long been a problem. Various springstructures have been suggested. The mounting of these structures in theframe of the chair or davenport has also in turn presented its problem.Y

The present invention provides a simple, rugged unit spring constructionpossessing in and of itself sufiicient support so that the use of theusual burlap or other fabric enclosing means heretofore employed isunnecessary. Further, since the spring construction is a unitary one,its installation is facilitated for it is handled as a unit and not asso many separate parts. The invention is also concerned with-a novelmounting for a unit spring structurewhereby, in a simple, economical andyet very satisfactory way, the unit spring structure can be positionedand supported in a chair or davenport.

The invention includes other objects and features of advantage, some ofwhich, together with the foregoing, will be apparent upon aconsideration of the structure disclosed in the drawing accompanying andforming a part'hereor" and incorporated herein to show the presentpreferred structure of the invention. I

In the drawing, Figure 1 is a View of the bottom of the upholsteringconstruction of the present invention;

Figure 2 is an enlarged fragmentary .view of the bottom shown in theupholstering construction shownin Figure 1.

Figure 3 is a section taken along the line of 3-'-3 in Figure 1, whileFigured is a fragmentary view of the top of the spring structureemployed.

In accordance with the present invention, the unit spring structure isfirst made up of a plurality of springs suitably joined together. In thedrawing, I have shown a plurality of double conical springs H, arrangedin a side by side relationship but spaced from one another, the springsbeing arranged in rows with the axis of any one The bottom of-thespringrunit is 'madefup in :a simple manner by crimping over sidewallsll of vU members I8. A U member is extended along each peripheral edgeof the spring unit and along each row of springs intermediate the endsof the spring structure whereby the several rows are joined together oneach side thereof. By simply crimping the U member on a segment of eachspring, a simple, strong, rugged and reliable fastening is assured.

To support a unit spring structure so provided in a simple manner in theframe of the upholstered piece, I preferably weave a plurality of springparallel to the axis of another spring. -,To'

secure the springs together as a unit and retain them, a wire framemember I2 is extended about the periphery of the outer springs and issuitably joined to peripheral portions of the springs as by metal clipsM. If desired tie springs 16 can be extended between diagonallypositioned springs H. to join themtogether and to provide additionalresiliency.

strap members 2! and HA across the bottom of each spring unit, eachstrap member being threaded through the spring structure, over and underthe several U membersJ End 22 of each strap member islsecured as. bynails 23 to one side 24 of the frame construction indicated generally at26, for the upholstered piece. The other end of each strap member isaperturedv as'at 21 to receive a spring 28 which is joined to theopternated that the end coils in each row are fully supported. Forexample, in Figure l, the two extreme strap members 2! pass under bottomof outermost springs H (at the top of the figure) while the middle strap2|A is passed under and then over U members [8. Inthis manner'theweaving is alternated to provide full support for the peripheral coils lI at both sidesof the struc-- ture. Inasmuch as the seat and backstructures of the davenport and chairs and the like are substantially ofthe same size, relatively few In I ac-' sizes of unit spring structuressuffice. cordance with invention, the unit spring structure can bereadily mounted .inthe frame of the upholstered piece and, when somounted, are

positioned to resist to a very satisfactory extent the wear and tear towhich such pieces are ordinarily subjected. i
